Feature:
1. The resistors are high-accuracy chip resistors to a good -to-noise ratio of the whole machine.
2. The use of special magnetic inductance for audio ensures that the sound is clear and powerful.
3. Using 1.6mm thick PCB double‑sided board, strong and , has a long service life.
4. The whole process of spraying tin to good passing performance of large and small currents.
5. Small size, easy to carry and store, convenient to use and with good performance.
